Apple on Wednesday mailed out its invitation to a Cupertino campus event next Thursday about its iPhone SDK. The intriguing part of the invitation is the promise of a roadmap for developers and for customers in the enterprise space.

Earlier this year, Cisco and Apple ended a legal spat when Cisco allowed Apple to use its "iPhone" trademark (though there was some debate whether Cisco really owned it). In return, Apple agreed to "explore opportunities for interoperability in the areas of security, and consumer and enterprise communications". Now in an ironic twist of fate, Duke university's wireless network is suffering from what appears to be a complete lack of interoperability between the new Apple iPhone and Cisco access points on campus. Network administrators at other campuses are keeping a close eye on the situation in case it becomes more widespread. LSU reportedly shut off access to its open wireless network on Monday as a preventative measure.
